A non-electric, portable lifting seat that can gently lift or lower up to 70% of a user's weight. It is adjustable for user weights up to 230 lb (104 kg). The hydro-pneumatic lifting mechanism of the Seat Assist engages as soon as the sit-to-stand motion is initiated by the user. Non-slip material on the base prevents shifting on seating surfaces and a built in handle makes carrying easy. Because it uses no electricity, the Seat Assist is perfect for restaurants, theaters, church or even a park bench. Washable, waterproof BLACK cover with comfortable memory foam cushion. * Note: Seat will lift up to 70% of a user's weight. Not intended for use with a wheelchair. Product weight: 8 lbs (3.6 kg).
